camview and camview-emc will not start was created by sajurcaju
For example:
camview-emc
Running glut init
RTAPI: ERROR: could not open shared memory (errno-2)
Segmentation fault
camview does exactly the same.
Any suggestions?
Thanks,
Steve

I should have added that I'm running Lucid 10.04 LTS.

Hi,
To be able to stand any chance of helping you we need to know exactly what you are doing and what the error messages are.
From a reboot, open a terminal and run linuxcnc from there.
Cut and paste the error output in the terminal and save it to a file in your config folder.
Run dmesg > dmesg.txt and save that in your config folder
Then zip your whole config folder and attach it to a post.
regards

I am not using LinuxCNC with camview (yet). Camview by itself, from a terminal, does not work. I rebooted, tried camview in a terminal and saved the error message and dmesg as requested. I did not include the results from linuxcnc since my problem occurs without it. I have not yet set up Axis with a camera.
If I run camview-emc, I get the same error message.
This was working fine before. Then I made the mistake of accepting an upgrade of Ubuntu to 12, which resulted in no linuxcnc. I reinstalled 10.04 and now camview does not work. Earlier (post 59326) I had a problem with linuxcnc not running, and per ArcEye's advice I changed to libgl1-mesa-swx11, which worked very nicely. That was when I had camview and camview-emc working, so I tried the same change now, with no success on camview this time. Linuxcnc works either way, but this is a different computer than the ancient one I was using in post 59326. This is the same computer I had camview and camview-emc working on before.
Thanks,
Steve

I cannot assist much here, I'm afraid.
The error is regards a segfault in one of the linuxcnc libraries
Which tends to suggest it is tied into Linuxcnc, so you probably cannot run it by itself.
I have not used it for over a couple of years and now don't even have a backup of 10.04, let alone a machine running it.
Hopefully someone who is using it can assist more

I realize that I have a workaround. Took me long enough.
The computer that I will actually use the camera on lives in the shop. That's where I run LinuxCNC and will want to use the camera. I also have LinuxCNC on a laptop in my office, just for trying things like the camera out.
I took the camera out to the shop and camview-emc works fine out there. So I will acquaint Axis and the camera out there, and leave the laptop as a mystery.
Thanks again,
Steve
